Data Analysis: The radiographs will be independently evaluated by 2 different board certified radiologists blinded to the clinical results and names of the patients. The films will be re-evaluated by each radiologist (they will be blinded to their initial reading) and the average of their results will be recorded. The clinical ASES and PENN scores will be recorded and differences in the preoperative and postoperative scores will be reported. Statistical analysis such as a students t test is not necessary as we are not comparing two groups however simple descriptive statistics will be used to report the change in ASES and PENN scores and most importantly the presence or absence of lucent lines and location of any lucencies. The lucent lines will be graded according to the method developed by Lazarus et al.4 The medical records and Xray data will be kept as confidential as possible under current local, state, and federal laws. The researchers will examine the medical records for information related to both of the shoulders and the study data. The medical records that identify the subject and the consent form will be reviewed by the researchers. The results of this research project may be presented at meetings or in publications. The identity of the subject will not be disclosed in any presentation or publication.
